Is monosodium glutamate a food additive?
Monosodium glutamate (MSG) is not regulated as a food additive. It is considered a flavour enhancing ingredient used to enhance the natural flavour of various foods. While there is no regulatory limit to the amount of MSG that may be added to food, the amount of MSG added should be at levels consistent with Good Manufacturing Practice (GMP). In other words, only the smallest amount needed to enhance the flavour should be added to the food.
